Abstract

A drill includes a housing and a motor having a drive spindle. An output spindle is capable of being rotationally driven by the drive spindle via a torque clutch. The drill further includes a tangential impact mechanism for superimposing tangential impacts onto the output spindle when activated. The tangential impact mechanism includes a sleeve rotatably mounted on the output spindle, and an anvil rotatably mounted onto the output spindle. The sleeve is rotationally driven by the drive spindle via a gear system at a first rotational rate when the torque clutch is not slipping and at a second rotational rate when the torque clutch is slipping.
